Not sure if they thought of this, but a request for the Wolve's Den

The core systems for the PvP arena were tested at the end of the beta;, you could duty finder with a queue or a party- it recruits 8 people for 4v4, but you can't use a full party. Naturally, since you could abuse it to trade wins, but I would like to request that you be able to form two teams of friends for an exhibition match that earns no points/rewards. While I personally enjoy all aspects of PvP, it would certainly be nice to play against your friends, and not just with them, even for no reward.

It has to depend on the potential PvP population. Ballista in FF11 is only a small percentage because there is no reward. You have to wait and see for now.
